react中配置setupProxy.js后localhost拒絕訪問的問題

//低版本配置代碼
const proxy = require('http-proxy-middleware')

module.exports = function(app){
  app.use(
    proxy('/api',{
      target:'http://localhost:5000',
      changeOrigin:true,
      pathRewrite:{'^/api':''}
    }),
    proxy('/api2',{
      target:'http://localhost:5001',
      changeOrigin: true,
      pathRewrite:{'^/api2':''}
    })
  )
}

修改為最新的配置，即可解決問題

//新版配置代碼
const {createProxyMiddleware} = require('http-proxy-middleware')

module.exports = function(app){
  app.use(
    createProxyMiddleware('/api1',{
      target:'http://localhost:5000',
      changeOrigin:true,
      pathRewrite:{'^/api1':''}
    })
  )
}
